I want to view dropdown in the shared page
<div class="navbar-collapse collapse">
    <ul class="nav navbar-nav">
        <li>@Html.ActionLink("Home", "Index", "Home")</li>
        <li>@Html.ActionLink("About", "About", "Home")</li>
        <li>@Html.ActionLink("Contact", "Contact", "Home")</li>
        <li>@Html.DropDownListFor()</li>
    </ul>
</div>
this above file name is _Layout.cshtml.
I have a table in my database named headings. in this table column as helps.
I want to add a button "Helps" along with "Home", "Contact", and "About". Such that when we click on "Helps" it shows a dropdown with all the values stored in the table headings in "helps" column.
How should I do it.
